The typical output characteristics curve for a transistor working in the common-emitter configuration is shown in the figure.

Define the dynamic output resistance of a transistor amplifier in common - emitter configuration.

The transfer ratio of a transistor is 50 . The input resistance of the transistor when used in the common-emitter configuration is 1 k ohm . The peak value of output current (in mu A) for an ac input voltage of 0.01V peak is

If the current amplification factor for a transistor connected in common emitter configuration is 100 and input resistance is 200 Omega , then the power gain is (Assume output resistance is 0.8 kOmega )

A transistor is used in the common emitter mode as an amplifier . Then

If a transistor is used in common -emitter mode as an amplifier,then

For a transistor the current amplification factor is 0.8 . The transistor is connected in common emitter configuration. The change in the collector curren when the base current chages by a 6mA is
